One Bangkok is a new urban development in central Bangkok. This mixed-use project will include offices, retail space, luxury hotels, residences, and cultural and social spaces, with a gross floor area of 1.83 million sq. m. The highlight of the site will be a 430-metre, 90-storey signature tower.

In February 2020, One Bangkok, Co., Ltd, together with CPAC Co., Ltd., and partners: K.C.S. & Associates Co., Ltd., Stonehenge Inter Plc and Italian-Thai Development Corporation Limited completed the largest continuous concrete pouring in Southeast Asia for the mat foundation of one of the first office towers.

The entire process took 33 hours and 15 minutes, with the successful coordination of 547 trucks providing a total 23,725 cubic meters of concrete.

Dextra was behind the connection of 2,200 tons of steel reinforcing mat foundation by supplying 500,000 units of Bartec standard couplers, transition couplers and headed bars.

Bartec standard and transition couplers were applied for various applications which require the joining of reinforcing bars, for example, column to column and beam to column connections.

The transition couplers allowed for the connection of two rebars of different size.

Headed bars were used as an anchor bolt to connect columns to a reinforced concrete foundation. This solution drastically alleviates the congestion of rebars:

Concrete foundation anchorage: bent bars vs. headed bars

Upon completion in 2023, One Bangkok will be a new global landmark destination in the heart of the city.
